SEL-2020 Instruction Manual
SEL-2020 COMMAND SUMMARY
Access Level 0
ACCESS Use this command to enter Access Level 1. Access Level 1 provides you with interrogate, read-only
capability. You will be prompted for the Level 1 Password if the SEL-2020 password disable jumper is
removed.
HELP Lists all commands available at the current access level. Use with a command as its parameter and it will
provide the syntax and a brief description of the command.
ID Displays SEL-2020 current ID, as set in the global settings, and the firmware identification string (FID
string). (See also WHO and STATUS commands.)
QUIT Causes the SEL-2020 to return control to Access Level 0 from Level 1 or 2. The command displays the
SEL-2020 ID, date, and time of QUIT command execution.
Access Level 1
2ACCESS Use to enter Access Level 2. Access Level 2 provides you with the ability to change SEL-2020 settings.
You will be prompted for the Level 2 Password if the SEL-2020 password disable jumper is removed.
AUTO n Displays the results of auto-configuration on selected port.
BROADCAST Establish direct communications with all IED ports simultaneously. To terminate communications and
return to command operation, use the termination sequence set for your port. (<CTRL-D> is the default
termination sequence.)
CLEAR m:n Clears data from the unsolicited message queue or from the archive data regions of an intelligent
electronic device (IED) port. Parameter m specifies which port (1-16). Parameter n may be BUF for the
unsolicited message queue or A1, A2, or A3 for the archive data regions. CLEAR m:BUF clears all
messages stored in the Port m buffer. Clearing an archive entry removes the oldest item from that queue;
subsequent entries remain. To completely clear an archive queue, add the parameter A (CLEAR 4:A2 A).
DATE Displays the date stored by the internal calendar/clock. Use a date parameter to change the date: DATE
mm/dd/yy.
DNPMAP Displays map of data available on DNP port.
IRIG Directs the SEL-2020 to read IRIG-B time-code input at the IRIG-B port. It updates the internal
clock/calendar time and date to the time code.
MAP m:n Displays the data structure and format for data stored in a port database. Parameter m = port number (1-
16). Parameter n = data region (GLOBAL, LOCAL, BUF, D1-D8, or A1-A3). Gives port data structure
and format if only port number is given. With both parameters, shows data region structure and data
address format.
MEM Displays the status of memory usage.
PORT n Establishes transparent communication between the master port issuing the command and the designated
printer or IED port. To terminate communications and return to command operation, use the termination
sequence set for your port. (<CTRL-D> is the default termination sequence.)
SHOWSET n Displays settings for the specified class or port number. Settings cannot be entered or modified with this
command. Change settings with the SET command in Access Level 2.
STATUS Shows SEL-2020 self-test status and the configuration, communication, and data performance of each
port. Type STATUS 4 to view the status information four times.
TARGET n m Displays global element or port-specific element information. Enter G for parameter n to display global
elements or enter 1-16 to display port-specific elements (the front-panel port has no elements). For
parameter m, enter the element row number you want displayed or enter ALL to show all of the elements.
You may add a repeat count as the third parameter.
